The Reds have suffered injuries to their bullpen during spring training each of the past two years. This time the rotation was thrown into flux from the start of camp. Latos went 14-7 last season with a 3.16 ERA in 32 starts. He had surgery to remove bone chips from his pitching elbow at the end of the season and had recovered well from that operation.

Latos felt something in the knee on one of his throws earlier in the week. An MRI found the tear, and he had surgery on Friday morning as the rest of the pitchers and catchers were having their physicals.
